Can Unique Widget ID's Be Set In Single Place?

[ccocco]

I need to set the "id" for every widget in my GWT application to help
our SQA Automation team be able to recognize and manipulate them
properly using the HP QTP tool. Is there a way to do this in one
place that all widgets would pass through (e.g. a factory, etc...) so
that I can intercept and format it with a prefix along with tacking on
the unique auto-generated identifier? Thanks!
